/** GridLogic
|
|
* The logic code for the luppp tracks / grid resides here. This logic is
|
|
* separtated from the Looper class so it can be repurposed by different
|
|
* controllers and input devices. The UI and eg. APC / Launchpad all have a
|
|
* similar grid style interface: the logic is implemented here once.
|
|
*
|
|
* The class sends Looper messages to change its state, thus abstracting away
|
|
* the details of the Looper control, and exposing its functionality using a
|
|
* convinient API.
|
|
*
|
|
* When the state of a block changes, it will update the state of the grid on
|
|
* the controller.
|
|
*
|
|
* It inherits from TimeObserver so it can change the state of the clip on the
|
|
* bar / beat.
